For a larger instance of Workfront, it would be beneficial to allow certain groups to opt in for capturing time at the project level (less mature groups that are still getting used to using a project management system). This way more mature groups can continue task level time tracking.
With current Workfront functionality, project level time tracking is a global setting. The more mature groups push back on turning this setting on, as it would potentially cause data integrity issues with tracking time at project and task levels. Less mature groups, who haven't tracked time previously, would like to the flexibility to track time at the project level to help with user adoption.
This would be an excellent Group Level Administration feature, the ability to customize hour preferences for different Workfront groups.
